I switched over tonight to AMSOIL 75W-140 severe gear. Slow rolled it to a parking lot and did some slow circles and turns. When the clutch is engaged and the rear is under load (light load) no noise. When I put in the clutch, during a turn, I can hear repetitive clunking back there, guessing that's chatter. Worried me so I babied it home and double checked levels to be correct. Drained a little and added 4 ounces of Ford differential friction modifier and did the same test. Same noise. So I think one of two things needs to happen:
1. Switch to AMSOIL 75W-85 severe gear (maybe the 140 is too much for this torsen limited slip rear end) and Ford additive, if still clunking.
2. Back to factory Ford gear lube with 4 ounces of additive.
I made a video but haven't uploaded it yet, but made no changes other than fluid change and these noises appeared.
It sounds like chatter to me, but if this is normal or part of break in, please let me know. No noise with clutch pedal let out, just when I push the clutch in, and even if I take it out of gear and let clutch up, same thing (during turns).
I'll take any ideas or thoughts you have about this. Let me know what you think before I dump this new AMSOIL
